How the odds work
Real numbers, no guesswork — here's exactly how your chances are calculated for every draw.
Every draw picks winning postcodes at random from the pool of active, registered UK postcodes. We're loading the current pool size…

Fairness, in plain English
The rules that keep every draw honest.
The 25-hour fairness lock
A postcode only counts as a winner if it was already on the member's account before the draw ran. Adding or switching to a winning postcode after the fact — even within the lock window — never matches.
Staff exclusion
PostDraw UK staff, contractors and their immediate households are excluded from every draw. Their postcodes never enter the pool.
Winner caps
Some draws cap the number of winners per slot so prize pools stay predictable — see each draw's rules below for its cap, if any.
Odds shown here are approximate and change daily as postcodes are registered, removed or excluded. They're calculated the same way for every visitor — there's no way to buy or boost your chances.
